Abstract

The invention relates to a preparation method for a nylon fan material used for automobiles. The method comprises the following steps: (1) adding silane coupling agent into nylon base materials containing a aid for coupling treatment, and sending into an electronic weightlessness steelyard; (2) sending flexibilizer into another electronic weightlessness steelyard, respectively baiting with the nylon base materials subjected to the coupling treatment, and externally adding alkali-free glass fibers while the nylon base materials are sent into a twin-screw extrusion machine for blending extrusiongranulation to obtain the nylon fan material. The surface of the nylon base materials is subjected to the coupling treatment to improve combination compatibility between glass fibers, and in addition, baiting is carried out in double electronic weightlessness steelyards to guarantee even and stable blending granulation. Compared with the traditional manual stirring, baiting and granulation, the method has the advantage of better performance quality.

Description

technical field [0001] The invention belongs to the field of automobile parts, in particular to a preparation method of a nylon fan material for automobiles. Background technique [0002] In recent years, my country's automobile industry has developed vigorously and has become a major country in global automobile production and sales. With the shortage of oil resources and rising oil prices, automobile lightweight has become a major issue in the development of the automobile industry, and the application of engineering plastics is an inevitable choice for automobile lightweight. The degree of plasticization of automobiles shows the manufacturing level of the industry. The interior and exterior parts of foreign cars all use plastic parts. The plastic used in automobiles exceeds 160 kg / vehicle. In recent years, the development and application of non-metallic structural parts has been vigorously promoted. Compared with metals, engineering plastics have many advantages such as...
